Summary of the invention
The utility model purpose provides a kind of boiler energy-saving coal feeder, and this device not only can improve boiler fired coal combustion efficient, energy savings, and simple in structure.
The utility model comprises the feeding-coal bucket be located on the body, be positioned at the coal supply tube of feeding-coal bucket end opening below and stretch into the defeated coal traveling-grate stoker of body of heater inner chamber, it is characterized in that, but the upside of the close body of heater coal feed point of described defeated coal traveling-grate stoker is provided with the water tank that is used to seal gap between body of heater coal feed point and up-down adjustment and the defeated coal traveling-grate stoker.
Remarkable advantage of the present utility model is: adopt the water tank type protective device; water tank has two interface tubes; its below interface is a cooling water inlet; its top is a hot water outlet; water tank can carry out up-down adjustment with respect to boiler furnace, can prevent that cold wind from entering burner hearth, reduces thermal loss; can prevent tempering, avoid fire to take place.
Simultaneously, the thickness when the water tank up-down adjustment can be controlled the coal seam and enters burner hearth makes burning zone more even, improves fired coal combustion efficient.
